COMBINATION FORCE AND PITCHER PUMP.

Application filed June 24, 1916.

To all whom it may concern:

Be it known that I, IVILLIAM JAMES GAL- LII-IAN, a citizen of the United States, residing at Kirkland, in the county of Coffee and State of Georgia, have invented new and useful Improvements in Combination Force and Pitcher Pumps, of which the following is a. specification.

The present invention relates to improvements in pumps, an object being to provide an attachment for ordinary pumps whereby the same may be readily converted into a force pump.

A further object of the invention is to provide a device of this character which may be readily attached to ordinary pumps, particularly pumps of the pitcher class, whereby the fluid from the well or cistern will be prevented from passing through the dis charge spout of the pump cylinder and de liver-ed, with force, to an air chamber or,

through a suitable pipe or hose provided for this purpose.

A still further object of the invention is to provide an attachment for converting an ordinary pump into a force pump, which may be readily positioned and which will perform the functions for which it is adapted with ease, expediency, and with accuracy.

A still further object of the invention is to provide an attachment for this purpose which will embody the desirable features of simplicity, cheapness and thorough efliciency.

WVith the above objects in view and others which will appear as the nature of the invention is more fully understood the improvement resides in the construction, combination, and the operative arrangement of parts illustrated by the accompanying drawings.

In the drawings Figure l is an elevation of an ordinary pitcher pump provided with my improvement.

Fig. 2 is a vertical longitudinal sectional view through the same, the piston rod being arranged to permit of the fluid flowing through the discharge spout of the pump.

Fig. 3 is a similar view illustrating the manner in which the piston rod is adjusted to prevent the opening of the plunger valve to allow the fluid to flow through the attachment.

Fig. 4 is a perspective view of the attachment.

Serial No. 105,666.

Fig. 5 is a horizontal sectional view through the same in applied position upon the pedestal of the pump. i

lVhile in the accompanying drawings, I have illustrated my improvement as applied to an ordinary pitcher pump, it is to be understood that the same is not to be thus limited in its useful capacity, as the said attachment may be applied to any ordinary form of fluid lifting devices.

F or a full understanding of the invention it is deemed necessary to illustrate and briefly describe the parts of an ordinary pump, which, however, do not form the subject-matter of the present invention.

In the drawings the numeral 1 designates the base or pedestal of an ordinary pitcher pump which has secured thereto a pipe 2 which leads to a well or cistern and which is normally closed by a foot or flap valve 3. As in the ordinary construction the pump cylinder 4 is removably secured to the pedestal 1, and the said cylinder is provided with an open pitcher top 5 having an outlet or discharge spout 6. The top of the pitcher 5 is partially closed by the usual flange member '7, provided with an extension 8 forming a fulcrum for a pivoted lever 9, the said lever having one of its ends provided with a plunger rod 10 which extends in the cylinder or barrel 4 and which has its lower end threaded to receive the yoke 11 of a plunger 12. The plunger includes a metal stop or seat 13 for a lift valve 14. Arranged upon the lower and threaded end of the plunger rod 10 is a nut 15 and this nut is adapted to be adjusted to hold the plunger rod against the valve 14 to prevent the opening of the said valve, when the rod has been adjusted to contact with the valve, to prevent the flow of fluid through the pump cylinder and through the discharge spout 6.

The foot valve is adapted to be swung to an open position upon the downward stroke of the plunger 11, and, of course, closed upon the upward stroke of the said plunger.

The above parts are common to the ordinary pitcher pumps, and as is well known in the art the cylinder or barrel is removably connected with the base or pedestal 1.

In carrying out my invention I disconnected the pump cylinder from the pedestal and arranged between the same a hollow cylindrical member 15 which is effectively retained through the medium of the usual connecting bolts between the said pump cylinder and the pedestal. This cylindrical member is provided with an opening which registers with the opening or bore of the pump cylinder and is disposed directly above but out of contact with the lower foot or flap valve upon the base or pedestal so as not to interfere with the action of the said foot valve. he cylindrical member 15 is provided with a threaded pipe extension 16, which is provided with a valve 17, and which may be also connected with an air cylinder or chamber 18. The air chamber is, of course, provided with the usual outlet 19 whereby a hose or pipe may be secured to the same, so that a great volume of fluid may be ejected therefrom when desired.

The improvement it will be noted, is entirely supported by the pump and while the same, as previously stated, is adapted generally for use in connection with a pump of the pitcher class the same may be also connected with an ordinary lift pump.

Also as previously stated the adjustment of the threaded end of the plunger rod 10 and the binding action of the nut for retaining the said plunger rod in proper position on the lift valve let readily converts an ordinary pitcher pump into a force pump.

The improvement, it will be noted, is in the nature of a casting, the ring or cylindrical member thereof, being of a size to be snugly received between the sections of the pump or other tubular members, the means for connecting the said members securing the said cylinder therebetween, and while I have illustrated and described my invention in connection with an ordinary pitcher pump, it is to be understood that the same may be successfully employed upon any ordinary construction of fluid lifting devices, as for instance, the same may be attached between two tubular members wherein the lower member is provided with a valve, similar to the valve 3 and the upper member has arranged therein a plunger provided with an operating handle, and the said plunger may be in the nature of a solid member, so that the valve 14; will be dispensed with.

Having thus described the invention what I claim is:

1. In a device for the purpose set forth, the combination with a sectional tube, and means for connecting the sections of the tube, the lower section having a valve there in, a plunger in the upper section, and operating means for said plunger, of a cylindrical casting arranged between the sections and connected thereto by the means securing the sections, said member having a pipe member communicating therewith, and a valve in said pipe.

2. In a device for the purpose set forth, the combination with a fluid lift including two tubular sections and means for connecting the said sections to aline the same, a valve in the lower section, a plunger arranged for reciprocation in the upper section, an operating handle for the plunger, of a cylindrical casting having its opposite ends flanged, arranged between the sections and secured to the said sections by the means connecting the sections, an angularly disposed integrally formed pipe member aranged centrally of the casting between the flanges thereof, and a valve for said pipe member.

In testimony whereof I affix my signature.

XVILLIAM JAMES CALLIHAN.
